           Summary: Akregator crashes closing a tab
           Product: akregator
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: gabrimonfa at gmail.com


Application: akregator (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
Akregator crashes closing a tab.
Meanwhile there was also another tab that was loading. The server was slow to
respond, so I was reading some other posts.
I don't think it is related to the specific rss, that I've read many times
without problems.

Yesterday I upgraded to KDE 4.7.3 in Kubuntu

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
